Kernrechtsfrage
Whether the 14 March 2003 cantonal judgment was an enforceable title under Art. 80 LP for definitive release of opposition.
Extrahierter Entscheid
No. The earlier judgment on liability was a prejudicial decision that did not become enforceable merely because no immediate federal appeal was filed; treating it as definitive title was arbitrary.
Extrahierte Begründung
A prejudicial ruling on a preliminary substantive issue becomes final only together with the final judgment if no immediate appeal is taken; optional immediate appeal rules do not oblige a party to use that route. Therefore the cantonal court misapplied Art. 80 LP.
